i want to go faster in second, and the number of teeth for a stock raptor is 13/40. so would the 14/39 combo be a good idea? or should i go 14/40 or 13/39? im so confused please just help. thanks.

u should know u work at a motorcycle shop!!!!

ya but still. is it better to change the front or the back? see i dont know everything!?!?! lol

Changing 1 tooth on the front is like going up or down three teeht in the rear and vice versa.

The front sprokets are cheaper. So financially the front is what you prolly ought to change.

will i broke the change because the back sprocket was rounded too much and i was doing some jumps and landing pretty hard so that prolly disnt help any. so i gotta get a whole set. thanks

Change to the 15T. I think Renthal has them. It has been gettin great reviews over at the raptorforum.com I run the 15 and wow it is pretty hard to keep the nose down. Oh and I am runnin 8.2 in the 1/8th mile
